I normally don't answer numbers I haven't assigned a name to, but this number has called me 6 day's in a row, all with in 5 minutes of the same time everyday. Today (1/10/19) I answered-but didn't say a word. After 30 seconds, the call disconnected.
This "spoofing" and "porting" of numbers so the consumer can't find out who is calling needs to be stopped by our government. but I won't hold my breath, given the current political status.
